A flaw was found in the Linux kernel. The rtl_usb_probe function mishandles resource cleanup on error. An attacker able to induce the error conditions could use this flaw to crash the system. The highest threat from this vulnerability is to system availability.
In order to mitigate this issue it is possible to prevent the affected code from being loaded by blacklisting the kernel module rtl8192cu. For instructions relating to how to blacklist a kernel module refer to: <https://access.redhat.com/solutions/41278> .
